The Role of Satellites for 5G and Beyond

Satellite systems are expected to play an important role in 5G and beyond wireless network systems. The vision of 5G is driven by the increased data rates and connection density, significantly reduced network latency, and optimized network efficiency. However, there are several use cases where standard terrestrial coverage is either not present or possible, making satellite systems uniquely positioned to provide a solution to bridge this gap. Satellite communication will play a significant role in 5G and beyond as a complementary solution for ubiquitous coverage, broadcast/multicast provision, aeronautical & maritime communications, emergency/disaster recovery, and remote rural area coverage. 

Recent years have also seen several advances in satellite systems and networks, allowing better efficiency, reliability, increased data rates, and new applications. By 2020-2025 there will be more than 100 High Throughput Satellite (HTS) systems using Geostationary (GEO) orbits but also mega-constellations of Low Earth Orbit (LEO) satellites, delivering Terabit per second (Tbps) of capacity across the world. 

The new systems will encompass a multi-layer aerial component with LEOs, HAPs, UAVs, and drones. New cost-effective system architectures such as cubesat and Starlink systems should be considered. Some of the  standards organizations like 3GPP (Release 16 and now Release 17) have been working on these Non-Terrestrial Networks (NTN). 5G and beyond 5G satellite systems have to meet the KPIs in terms of peak data rates, spectral efficiency, connection density, e2e latency, delay jitter, and mobility.

This vertical track is intended to be a forum where professionals from government, industry, and academia have been invited to present original contributions and their ideas. lt is also an opportunity to discuss the key challenges and integration of satellite systems to 5G and beyond. The 5G-Satellite Vertical track will include a keynote talk, invited speakers, and a panel session.

Some of the major considerations that this vertical would like to address include: 

  • New use cases for 5G and beyond 5G satellite systems, 
  • Edge computing applications in future satellite systems,
  • Machine learning and AI applications.

Title: The future of Satellite-Terrestrial 5G system and service integration

Abstract: We are experiencing a massive societal transformation through the digital enablement of our world. The demand for connectivity for consumer and business continues to outstrip our ability to deliver services everywhere. The cost of rollout of wireless services into wider area is a major blocker to the productivity of rural and remote communities. Satellites could contribute to the solution, but current satellite systems are constrained by spectrum utilisation, and regulatory constraints on power flux density driven by a historic perspective on spectrum sharing between satellite and terrestrial systems.
The world is changing, the cost of manufacturing satellites and the access to space is dramatically falling, new materials such as flexible photovoltaic and lightweight composite structures, together with virtualised network functions and software radio platforms increases capability and flexibility. New paradigms such as megaconstellations are manifest, triggering significant investments in future constellations.
This talk outlines some of the opportunities that are driving the investment, and considers a number of future operational scenarios. To stimulate the imagination, a future concept for synthetic aperture communications satellites is described, able to deliver massive spectrum reuse and direct service delivery to future smartphones as an overlay to 5G.

Title: Potentials and challenges of MEC implementation in B5G Satellite Networks

Abstract: Multi-access Edge Computing (MEC) concepts have been out for already many years with particular interest and application in terrestrial networks where MEC was initially defined as mobile edge computing. In this respect, MEC has been exploited for both computation and caching purposes with the ultimate need to achieve a more flexible and efficient overall architecture and, more importantly, to minimize the service execution delay so as to approach the so-called concept of almost-zero perceived latency. Such a perspective is becoming even more attractive in the context of B5G where non-terrestrial networks (e.g., encompassing satellite systems too) are expected to be integrated with the rest of the telecommunication ecosystem. Initial studies have been already carried out around the use of MEC in satellite systems especially for boosting the access to content but a more holistic view on potentials and challenges is still missing. In particular, the advent of 3D satellite network with several space objects possibly interconnected dramatically multiplies the opportunities for exploiting MEC concepts, although also design limitations have also to be properly understood and taken into consideration. As such, this talk attempts to provide a general view on the different opportunities that can materialize in the context of integrated satellite-B5G networks and identifies some key research topics for further development and investigation from the scientific community in the very next few years.

Title: Dense LEO Satellite Networks: Opportunities and Challenges.

Abstract: The future generation of Internet services expect ultra-low latency, very high density of nodes, high throughput, and high reliability. The evolution of computer networks beyond 5G to support future Internet services is likely to be influenced by the emerging class of dense LEO satellite networks. Recently proposed dense LEO constellation networks such as Starlink and OneWeb provide better latency performance across continents than that can be provided by the optical fiber-based backbone of today’s Internet. Therefore, many futuristic services of the Internet may move over to the dense LEO clusters. However, the dense LEO clusters face many technological, operational, and research challenges. This talk focuses on opportunities and challenges offered by the dense LEO satellite networks.
